Abstract

The invention provides a sand liquid circulation system of a wet shot blasting machine. The sand liquid circulation system comprises an impeller head unit used for mixing sand and liquid together or separately throwing the sand and liquid to a strip steel; a sand liquid collection box arranged below the impeller head unit; a conveyor unit used for conveying sand deposited at the bottom of the sandliquid collection box to the impeller head unit; and a filter unit for filtering and separating san-containing waste liquid containing iron oxide powder and a part of sand from the sand liquid collection box, and the filtered liquid obtained through the filter unit is transported to the impeller head unit through a pipeline. According to the sand liquid circulation system provided by the invention, high-pressure liquid is no longer used as a carrier for transporting the sand, and the sand can be directly transported to the impeller head unit or even a jet port, so that the descaling effect isimproved.

Description

technical field [0001] The invention belongs to the field of strip steel descaling and relates to a sand liquid circulation system for wet shot blasting. Background technique [0002] In the production process of the strip steel, especially in the hot rolling stage, a layer of iron oxide scale is formed on the surface of the strip steel. In the subsequent production and use of the strip steel, the iron oxide scale must be removed, that is, the scale of the strip steel Skin. [0003] At present, there are mainly two methods for large-scale removal of strip steel scale. One is to use strong acid to clean the strip steel. Although this method is fast in removing scale, it cannot avoid a large The production of waste acid results in environmental pollution; another method is to use sand and liquid projection technology, that is, to mix sand and liquid into a slurry or to shoot them independently on the surface of the strip through a shot blaster. The beating and friction of th...
